OK, I cannot rebuild ghc-6.8.3 on a ghc-6.8.3 existing enviornment, very
good.

What is almost certainly going on is that mtl has been rebuilt but the other packages that depend on it (like http) have not.
I wonder if we could detect this better in ghc-6.10.2. There are ABI hashes available, so if we could record them in the package registration info then we should be able to detect when a dependent package has changed ABI. The longer term solution is to use a nix-style persistent package store.
The short term solution in this case is probably to rebuild the HTTP package.
